Why does my action not play after another action?
First method (but dont know if that'll work):





Second method (more complicated but works defenitely):




Add a game-property to your enemy. ( + Add Game Property )
Set it to boolean and checked (= true). (See red boxes in the image)
Connect the collision-sensor to a property-actuator.
This actuator has to set the property to "false".
Add a property-sensor for each action-actuator. While the property is true (enemy alive) the walk-animation will be played, when the property is false (enemy dead) the die-animation will be played.
